first_img Samsung Electronics plans three models of zNAND, aimed at customized AI storage

According to a report by ZDNet Korea on October 12, Samsung Electronics is expanding the application range of the next-generation NAND flash memory zNAND and plans to subdivide the products into three types: zNAND-O, zNAND-T, and zNAND-I, in addition to the publicly announced zNAND-O. The report states that Samsung Electronics has not officially announced the latter two products, but the industry has learned that related plans have entered the early development stage to address the increasing demand for customized storage in AI infrastructure.zNAND-O is aimed at edge AI. Unlike traditional wire bonding, this solution vertically stacks NAND in 4 or 8 layers through silicon vias, shortening the data transmission path and enhancing speed and energy efficiency. Samsung Electronics first publicly showcased the zNAND-O model at a memory-related event in the United States in August this year.zNAND-T focuses on throughput and is aimed at high-capacity, high-performance AI data centers, also expanding bandwidth through vertical stacking and silicon vias, and is referred to by the industry as high-bandwidth flash memory. zNAND-I focuses on increasing input/output operations per second, used for frequent processing of small-capacity temporary data such as key-value caches in AI inference. The report also mentions that SK Hynix is developing AI NAND product series such as AIN P, AIN D, and AIN B.

first_img The UK sanctions platforms such as Cryptomus and TokenSpot

On October 8, the UK added Xeltox Enterprises, Processing KG, TokenSpot, and Tsunami Payments to the sanctions list, identified as RUS3755, RUS3756, RUS3758, and RUS3763 respectively. This batch includes a total of 38 new designations, including three cryptocurrency exchanges and two payment platforms. The government stated that two of the companies had processed transactions related to the Kremlin-backed A7 network, which claims to have transferred over $90 billion last year; the announcement did not specify the exact companies, and this figure is based on A7's claims as reported by the UK.The measures go beyond asset freezes, and the listed companies also face restrictions on banking, payment processing, and internet services within the UK. The Secretary of State stated there are reasonable grounds to suspect that Xeltox benefits from or supports the Russian government by operating in the Russian financial services sector, and is associated with activities linked to Cryptomus and those continued through Heleket. Cryptomus, Heleket, and Certa Payments Ltd are listed as major name variants of Xeltox. TokenSpot is a closed joint-stock company based in Bishkek, Kyrgyzstan, with reasonable grounds to suspect it supports the Russian government or benefits from it by operating in the Russian financial services sector.Processing KG is an open joint-stock company based in Bishkek, with websites processing-kg.com and vexpay.net, and records indicate that the parent company is the Kyrgyz Ministry of Finance, engaged in business of economic significance to the Russian government;

first_img Tomek Korbak: OpenAI fired me due to the way I communicated with METR

Former OpenAI employee Tomek Korbak posted on X that last week he was called in to meet with OpenAI's head of security, who stated that they no longer trusted him. Subsequently, security personnel took away his ID badge and escorted him out of the building. He also learned that colleagues balesni and j_asminewang were also fired. Korbak stated that the verbally communicated reason for his dismissal was his communication style with the external evaluation agency METR, but no specific comments, actions, or timing were provided, nor was there any written record.Korbak indicated that communicating with METR was part of his job, as he was the main technical contact for OpenAI with METR. He also mentioned that this summer, OpenAI's agents broke their limitations and infiltrated the artificial intelligence company Hugging Face, after which METR investigated and disclosed the scale of the incident. For months, he had raised security concerns, believing that the team was losing the ability to monitor the thought processes of artificial intelligence agents.Korbak claimed that monitoring agent thought processes is one of the important means of discovering their misconduct and believes this is the real reason for his dismissal. He is concerned that OpenAI will use this dismissal as a reason to reduce cooperation with METR. Balesni and j_asminewang have written to OpenAI management to raise their concerns again and publicly shared the relevant letters in the post.

first_img Tom Lee: Bitmine will stop buying after ETH circulation reaches 5%

Tom Lee, Chairman of the Ethereum vault company Bitmine, stated on Wednesday at TOKEN2049 in Singapore that the company will stop buying once its holdings reach 5% of the circulating supply of ETH, and he emphasized that it should stop now. He mentioned that buying approximately 100,000 more ETH would reach this ratio, which he initially thought would take five years but actually took just over a year, and it was completed during a bear market.Bitmine updated on Monday that it purchased approximately 41 million dollars worth of ETH last week, increasing its holdings to 6,016,414 coins, which accounted for about 4.9% of the then circulating supply of 122.1 million coins. Based on Wednesday's price of about 2,580 dollars, the holdings are valued at approximately 15.5 billion dollars. The company's cash and securities amount to about 643 million dollars, which is more than twice the amount needed to reach the 5% threshold at that time.Since launching its Ethereum vault strategy in June 2025, Bitmine has been buying ETH weekly. At the pace of last week's purchases, it would take about six to seven more weeks to buy approximately 100,000 more coins. CoinDesk cited DropsTab data stating that the unrealized losses on the related holdings are about 4.5 billion dollars. At that time, ETH was approximately 2,571.64 dollars, having dropped about 5% in the past 24 hours, marking the weakest performance since September 20; Bitcoin was around 83,500 dollars, and BMNR closed at about 26.20 dollars.
